signor to News Projection Corporation, New York, N. 'Y., a corporation of New York Application September 25, '1931,-SerialiNo.'565,085 Renewed January 9, 1935 14 Claims. (ours-42) This invention relates to stock quotation projecting machines in general and more especially to stock quotation projecting machines associated withhigh speed motor-driven tickers.

.With the high speed motor driven tickers today in use, it is possible to produce the printing impression on the tape without interrupting the feeding operation. In view thereof, it isan object of the present invention to provide an improved stock quotation projecting machine associated witha high speed motor driven ticker in which the tape is continuously being "advanced and as a result of which-the last quotation printed before a periodof rest, will be advanced into projecting position although the printing operation of the ticker maybe interrupted for a-greater or lesser period.

' It is still another object of the present invention toprovide an improved stock quotation projecting machine associated with a high speed motor driven ticker in which a rewind :reel alone is depended upon fordrawing the tape across the light aperture without the useof any independent tape puller, or tape movement control device.

It is still another object of theipresentinvention to provide an improvedstoek -quotationzprofleeting-machine in which little if any'attention need be paid to the speed of 'the tape pulling motor other than to-determine its speed to equal or exceed the speed of the tapeasit is advanced to the-light aperture bytheticker It is still another object of the present invention to provide an improved stock" quotation projecting machine in which a high speed motor driven ticker maybe eonvertedin-to a continuously feeding device without'affecting in anyway any of the numerous actuating parts associated with the printer other than the actuating parts of the feed-mechanism.

These and other features, capabilitiesand ad- :vantages of the invention will appear from the subjoined detail-description of one specific embodiment thereof illustrated in-the accompanying drawing in which Figure 1 is a front-elevation of a stock'quotation projecting machine made according to the present invention; r

Fig. 2 is a fragmental side elevation partly in section of the same;

Fig. 3 is an enlarged detail view showing the mechanism for actuating the feed roller used in the present invention; and

Fig. 4 is an enlarged end view of'the mecha- "nism shown in Fig. 3.

" In the emb'ofilment "shown, thetape T passes from :the supply 'reel I of the ticker :2 mounted 'on theaba'se :3 to the IightaaperturefQrmed at the upperend'ofthe extension 4 of the lamp housing :5 containing the lamp '6 from which the light rays passthroughthe lenses 1 and 8 to the de- 5 flector 9 'by :which they are deflected upwardly to the light aperture and the tape passing across the same to the objective lens contained in the housing I 6 secured to the bracket H extending from :the upper end of the extension 4. The 10 light irays will then pass up to the deflector l2 fromwhich they are-deflected onto the deflector l3 from which they are in turn deflected onto the screen 14.

From Jthelight aperture formed-on the extension L-the tape then passes down onto the rewind reel l5 mounted on the shaft 16 journaled in the bracket ll on which there is mounted a pulley -I8 which is connected by the spring belt 19- with the pulley it -on the shaft 2! of the 20 m0tor 22.

The ticker 2 in the present instance as illustrated, is a high speed motor driven ticker of the type recently adopted by the New York Stock Exchange, which is equipped with a motor 23 having =a-drive shaft "24 on which is mounted the=motorl-pinion 25 in mesh with the type wheel shaft gear-26 andthe main shaft gear '21 mounted on a shaft 28 on which is mounted the motor control .pinion 29. 30

The gear '26ismounted on the shaft 30 of the typewheel stop =unit3l at the end'of which shaft is mounted the type wheel 32. Themotor control pinion 2-9 meshes with the motor control gear 33 to which in the .present instance the continuously-operating tape feeding means are connected.

The tape feeding roller 34 in the high speed motondriven ticker heretofore in use was intermittentlyactuatecl. In the present instance, this intermittentactuating mechanism has been removed and the roller 34 mounted on the shaft 35at the-end of which is secured the beveled gear 36 in mesh with the beveled gear 31 at the lower end of the shaft 38, the upper end of which is provided with a beveled gear 39 in mesh with the beveled "gear '40 on "the horizontally extending shaft 4| at the end of which is mounted the driven gear "42 in mesh with the motor control gear 33 and as a result of which the feed roller "34 willbe'c'ontinuously operated when the ticker motor 23 is operating.

'The roller'34 in the present instance is maintained in engagement 'with the tape T by the pressure roller 43 of standard construction mounted on the bracket 44 and urged into tape engaging position by the spring 45. The bracket 44 in the present instance is provided with the usual tape guide arm 46.

In operation, the speed of the rewind reel l 5 at the start need only be determined to correspond with the tape advancing speed of the tape roller 34 since due to the increasing diameter of the tape roll on the rewind reel [5, the tape pulling speed will ordinarily tend to increase so that any slack that might be built up in the tape T due to the stretching of the'tape would be quickly taken up as the diameter of the tape roll increased, or else the initial speed of the rewind reel l5 slightly exceeds the tape advancing speed of the tape feeding roller 34. The spring belt I9 will of course compensate for the excess of the speed of the rewind reel 15, if any, as compared to the tape advancing speed of the tape feeding roller 34.

From the foregoing, it will thus be seen that the rewind reel l5 will constantly maintain the tape T smoothed out at the light aperture and the movement of the tape across the light aperture be maintained uniform to correspond with the uniform tape feeding movement imparted to the tape by the tape feeding roller 34 and thus dispense with a uniformly operating tape pulling roller in addition to the rewind reel.

From the foregoing, it will also be seen that when the tape pulling motor 22 is started, it will tend to impart a rotative movement to the rewind reel which will slip in relation to the spring belt l9 so long as the ticker motor 23 is at rest, and that as soon as the ticker motor 23 starts operating, the tape feeding roller 34 will start its feeding action and continue to feed the tape T toward the light aperture in turn to permit the rewind reel 15 to take up the tape and draw it across the light aperture after so being discharged or advanced by the tape feeding roller 34.

In view of the foregoing, if a message is transmitted or a series of quotations are transmitted and the printer comes to rest the last quotation will continue to advance in the ordinary tape feeding period required to advance from the printing point to the light aperture and as a result of which the last quotations of a series located between the ticker and the light aperture will not be concealed from view any longer than the ordinary time required for them to advance from the printing point of the ticker to the light aperture.

From the foregoing, it would also appear that the standard high speed motor driven ticker can with facility be converted into a continuously feeding tape device without any reconstruction by merely the omission of the heretofore used intermittent tape feeding actuator and the replacement of the same with an actuating connection connecting the standard tape feeding roller 34 with the standard motor control gear 33.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
